Give edit access to dashboard

Hello

I created a dashboard with a few preliminary charts for the product team.  But they want to add additional charts on the dashboard on their own.  It’s easier for me to create the initial template on the dashboard and they can add/modify to fit their needs with additional charts.  But how do I (creator of the dashboard) give the Product team and their users (receivers of the dashboard) edit access to the dashboard so they can make changes on their own?  I currently have ‘user’ level Role as do the members of the Product team.  Thanks
